[RESOLVED] Why return 3 still equals true?

[ifubad]

<?php
    function foo() {
        return 1;
    }

if (foo() == TRUE) echo "true";
?>

function returns 1 equals true, but if I change the 1 to say 3, it still returns true. Why is that?

Thanks in advance

try changing it to 0.

then, try changing == to ===.
